My form suspends because I haven't typed one person's name in a user task. 

The form works with the User Task if a licensed user's name is typed in, of course, but all attempts at trying to get it to pick the same users based on a variable fail, except the Team option which can't be used because it allows everyone in the team to see everyone else's form submissions.

• First Try:  User Task is set to a variable that is a drop down pick populated by a lookup (the form is submitted after the first user picks the name of his supervisor that will be approving his form).
• Second Try:  Created a Single Line field (hidden field) to populate whatever approver name was picked and used that Single Line variable for the User Task.  Still Suspended.
• Third Try:  Created an ORG TEAM and entered all employees names and assigned ROLES for each employee job position, so I could use teams filtered for someone like Accts Payable Clerk.  Then made the User Task assign to the ORG TEAM but with a filter to pick one name out of the team based on the variable for Approver_Name.  This works using the same variable in the filter that DOESN'T WORK when using the variable as a simple user name without going through a team!??  It can't remain this way, because it will allow everyone in the ORG Team to see everyones' Expense submissions (private information!).  So I have to remove this configuration.

What am I doing wrong with the variables without using a team?
